Feeler: headers wanted

Looking to see if anyone here in the club has a nice useable set that'll fit in the 9c1. If not, someone school me up on what to do/not to do, what to get/not get. I've never put these in a b and could use as much info as is available. Id like it all to end up using oem cats and an aftermarket catback setup. Its my understanding the AIR bung equipped headers are more $. I dont want to touch my ecm yet, so those would be a plus. Thanks guys!

Excellent. Thanks Tim.
